Pyridine is a water-soluble liquid and the parent of many biologically important compounds.
Surface Forms
Morphology
pyridine = pyrid + ine
A technical chemical name formed from the combining form 'pyrid-' plus the chemical suffix '-ine'; the components are not productive standalone English words for average learners, so the meaning is not derivable.
Etymology
The word pyridine comes from the Greek root pyr, which means 'fire' and is the same root in pyrotechnics. Early chemists found this liquid by heating coal tar, so the name reminds us that pyridine is a flammable, often toxic chemical used in making other compounds.
